If you use the BLO/Mineral Spirits (I like turpentine), put the thinnest coat possible. Just put a dot on the stock and rub it until it will spread no farther. This will liven the stock back up without a heavy coat. Will normally dry in 24 hours. If your stock has a little accumulated grunge, apply a heavy coat of the BLO
/MS and let it set about 30 minutes. Then scrub the coat off with toweling, and smooth out any that is left. It probably won't need another coat after this, but if so, apply as noted above.
